Fig. 16 shows the selvage thread as being led into the margin of the fabric with a weft thread looped thereover, also showing a selvage-forming wire as positioned in the'usual way in the margin of the fabric, which wire is not connected to the selvage thread carrier.

It has been found in practice, particularly in the operation of looms for weaving fine silk goods and also looms for weaving very coarse goods that where the weft thread is carried in the shuttle, very frequent replenishing is required; to overcome this important and very objectionable feature of weaving, I have provided an attachment for a loom wherein the weft thread supply is not carried in the shuttle but at a point outside the shuttle and is led thru the shuttle and by it laid into the fabric being woven, and in order to accomplish a weaving operation with this style of shuttle, as the shuttle is passed over and back thru each open shed I lock the loop in the fabric by providing a selvage thread separate from the rest of the warp threads and support the supply package of this selvage thread at a point adjacent the edge of the fabric being formed; means being provided for looping the weft thread over the selvage thread to lock the same into the fabric and prevent this weft thread from being drawn into the fabric by the returning shuttle. In some instances, I also employ a short selvage-forming wire in the margin of the fabric and attach one end of the wire at a point adjacent the selvage thread supply and in such position that as the weft thread 1s being looped over the selvage thread it is likewise and simultaneously looped over the selvage-forming wire, which wire serves to support the selvage thread against the pull of the shuttle and serves to form a much smoother selvage edge in the fabric; and the following is a detailed description of the present embodiment of my invention and showing one construction of loop-forming device by which these advantageous results may be accomplished in the loom:

lVith reference to the drawings, 10 designates the usual breast beam of a loom, 11 the cloth take-up roll, and 12 the lay on which the shuttle 13 is caused to travel back and forth to position the warp thread'li in the fabric 15 being formed.

Instead of employing the usual type of shuttle which carries the'weft thread, I mount a large weft thread supply bobbin 16 on the floor or other convenient place adjacent the loom and lead the thread up thru the tension device 17, the guide eye 18 and thru the longitudinal slot opening 19 in the base of the shuttle 13 and thru the guide eye 20 to the fabric 15 being formed.

This shuttle may be caused, by any of the usual methods, to travel back and forth across the lay, and the lay caused to swing on its pivot 21 forward and back in the usual way. One of the features of my invention is the provision of a simple and effective device for causing the weft thread to be looped automatically around a selvage thread during the weaving operation. One means for accomplishing this looping operation is the arm 22 which is formed in halves secured together by bolts 23, the whole being fixedly mounted upon the breast beam 10 to project rearwardly over the lay when swung to its forward position, as best illustrated in Fig. 1. The memb rs at the free end of this arm are curved away from each other as at 24, forming a space between and these inner curved surfaces are grooved as at 25 to loosely receive between them the opposite side edges of the selvage thread carrier 26 and the extremities of these arms are reduced to form tapered fingers 27 which are spread to form an open mouth 28 to facilitate the entrance of the weft thread thereinto, in order to be passed around this carrier.

This carrier member 26 has a relatively thin oblong body portion which is pointed at its opposite ends. And has a hollow center portion as at 27 in which a selvage packagespool 28 is rotatably mounted on the pin 29. A spring 30 compresses against the spool end and provides the necessary frictional tension on the selvage thread 31. This selvage thread is led from this spool or package up thru the eye 32 in its carrier and across into the margin of the fabric 15 being formed, as best illustrated in Figs. 15 and 16.

In some instances, where my improved loop-forming mechanism is employed, more particularly in the weaving of elastic webbing and the like where a smooth selvage edge is especially desired, it is found of advantage to weave or loop a marginal wire 33 into the selvage as best illustrated in Fig. 15, and to attach one end of this wire to the carrier 26 so that as the weft thread is passed around the carrier 26 to be looped over the selvage thread 31, it is simultaneously looped over this selva forming wire 33 which wire then assists in taking the pull of the weft threads as inserted by the shuttle in being carried across the loom.

As this weft thread is beaten up into the fabric, the tension on the selvage thread and also that of the selvage-forming wire 33 serves to draw this loosely floatin carrier 26 forwardly slightly in its groove between its the fabric being formed to extend rearwardly over the lay when swung to forward position, said arm being forked at its free end presenting spaced fingers for guiding the thread into the space between said fingers, a floating carrier for the selvage thread located between said fingers, a bobbin in said carrier from which a thread is led to the margin of the fabric, and said carrier having a thread-guiding surface whereby the swing of the lay moves the shuttle forward and back to pass the weft thread between said fingers to be engaged by said guiding surface and conducted under and over the carrier to loop it about the selvage thread.
